CASH-CAR SYSTEM.

Application filed May Y, 18 83. (No inodcll f all whom it nuty concern..-

Be it known that WeJBYROiv A. Oscoon and EDWIN P. OSGOOD, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new andusefulIm-proyement in Cash- Car Systems; and we dohereby declare that the following is a -full, clear, and exact description of the same.

Our invention relates to cash-car systems in which a car is carried back and forth upon an elevated track extending from difl'erent parts of the store to the cashiers desk.

It consists in special means for supporting andstretching the wires, and of a spring buffer or stop adapted to receive the car and prevent rebound at the terminus of the route.

In the accompanying drawings, Figure 1 represents a plan of one form of supporting device with wires extending radially to differ ent parts of the store. Figs. 2, 3, and 4 represent pins in side elevation,to which the wires are attached, aiid by means of which they are tightened. Figs. 5 and 6 represent the Fig. 7 shows a side spring buffer and catch. elevation of the wire track.

Heretofore the elevated tracks or ways used in cash-car systems have been stiff, trussed, or rigid ways supported at suitable intervals on brackets whichwere constructed to allow the ear to run by the said supportingbrackets. These forms or ways are unsightlyand require c )nsiderable time to put them up-a matter of considerable importance when a store is unavoidably occupied during the entire day. To remedy this difficulty we use a stretched wire for the way on which the car is to run, and supporting devices at each end adapted to hold the wire under proper tension, so as to prevent too much sagging.

' In the drawings, a supporting device is shown in Fig. 1 at A. From this wires D D extend to various parts of the room. One of these wires is shown in Fig. 7 attached at one end to support A and at the other end to support E. The support at one end is provided with astretching device fon eaclrwirer By this means supports are required only at the ends, and the car may be suspended from a wheel or wheels, which run upon the wire without obstruction.

Various means may be usel to put-the wires under tensiontmd hold them in that condition. The means shown in the drawings consist of a ring, A, provided with spokes a a and a. hub, b. This ring is suspended by a rod fixed in thehub. The ring is provided with a series of holes, a, in which are set the pins sustaining the wires. These holes are made vertically through the ring, as shown clearly in Figs. 2 and 8. In Fig. 2 the pin B isformed with a head, or is otherwise adapted to be turned by'a wrench- The part which enters the ring is reduced and fits asmooth hole. The shoulder rests upon the upper surface of the ring, and a nut, d, is turned onto the lower end of made in the upper part oi' the pin, through which the wire is introduced. Whenever it is desired to put strain upon the wires, the nut (l is loosened and the pin turned to wind up the wire, and when the wire is wound up sufficiently the nut is turned up to hold the pin in place. Instead of placing the nut below and'75 the hole in the ring smooth, the hole may be threaded and the nut put in above, as shown in Fig. 3. The wire being drawn through the hole inthe pin and secured inany convenient way, the pin is turned sufficiently to give the desired strain, and then the jam-nutf is turned down to jam against that face of the ring and hold the pin securely.

We may use instead a tapering pin, E, (shown in Fig. 4,) and fit it to atapering hole in the 8 5 ring. After this is turned it may be forced inward by a light blow sufficiently to hold it from turning byfrietion. Other means may be employed for holding the pin. The ring may be sustained by the radial wires, or by guys in the direction in which wires may not be used, or may be suspended from the ceiling. The ring is required when the position of the cashier s desk is central. Then it is at the side, a half-ring, or a straight bar, or any 5 It is suspended from wheels m m, which are in the form of pulleys and run on the track, the suspending-straps being on one or both sides of the wire. The wire is stretched approximately level, and the car is impelled from station to station by a push, that being suflieient for the purpose.

In order to prevent rebounding when the car reaches the terminus of the track, we pro vide a spring, which acts as a catch and buffer. This is shown in Figs. 5 and 6, in which 0 represents a spring, which may be of fiat or round metal. The two arms extend above or below the track and parallel therewith. The ends of the arms are flared outward to receive the forward part of the car, which thus opens the arms and passes between, being firmly clamped and held therein. Thus the force of the shock is broken and rebounding prevented.

The main object of the buffer being to stop the car, we do not confine ourselves to a mere spring-buffer to receive and hold the car, as

1. I11 combination with the suspended wires of a railway cash system, a supporting bar or ring and pins set therein, and adapted to be connected to the wires and to turn to wind up said wires, said pins having suitable retaining devices, substantially as described.

2. In combination with the wires and supporting bar or ring of a cash-car system, an arresting-stop or a springbuffer adapted to receive and hold the car.

In testimony fwhereof we have signed our 3 names to this specification in the presence of two subscribing witnesses.
